Question

这是一个将公里数转换为英里数的程序，但是，每次运行它时都没有要求输入的行，因为它应该是，而是始终为空。

以下是代码：

KILOMETERS_TO_MILES =float(0.6214)

def main():
    Distance = input("please input the distance in kilometers to wish to convert:"))
    showMiles(Distance)

def showmiles(Distance):
    miles = Distance * KILOMETERS_TO_MILES
    print=("Conversion of ", Distance,"kilometers to miles: ", miles, "miles")

main()

Answer 1

这应该有效：

KILOMETERS_TO_MILES = 0.621371

def show_miles(Distance):
    miles = Distance * KILOMETERS_TO_MILES
    print('Conversion of {} kilometers to miles: {} miles'.format(Distance, miles))

def main():
    Distance = float(input("please input the distance in kilometers you wish to convert: "))
    show_miles(Distance)

main()

您的原始代码有几个问题：

KILOMETERS_TO_MILES =float(0.6214)

def main():
    # You have an extra closing ')' on the next line
    Distance = input("please input the distance in kilometers to wish to convert: "))
    showMiles(Distance)  # this showMiles has an upper case 'M'

def showmiles(Distance):  # this showmiles has a lower case 'm'
    miles = Distance * KILOMETERS_TO_MILES
    # You have an = sign on the next line that shouldn't be there
    print=("Conversion of ", Distance,"kilometers to miles: ", miles, "miles")

main()

Answer 2

看起来问题的一部分来自你的第三行。我注意到你有两个右括号'））'但你只有一个打开'（'。 ” ..
